Nothing of importance actually.
Just reporting it.

It looks OK on my end, I wonder if it's not the public key that has expired and you might need to redownload:

gpg --keyserver hkps://keys.openpgp.org --recv-keys 70938C780679EE98

Indeed! This added 3 new sigs:

>gpg --keyserver hkps://keys.openpgp.org --recv-keys 70938C780679EE98                                                
gpg: key 70938C780679EE98: "Adrian <adrian@mxlinux.org>" 3 new signatures                                                                            
gpg: Total number processed: 1                                                                                                                       
gpg:         new signatures: 3

Seems like I had an outdated sig, from another keyserver.
Sorry!!! :-)
